Core Product Characteristics
Supports 7 types of configurable input signal logic, compatible with both normally open and normally closed field contacts; first-out fault identification function to lock the earliest triggered alarm for rapid troubleshooting; five standard LED flash modes complying with industrial alarm standards; non-volatile EEPROM memory stores all parameter settings without battery backup; full hardware and software self-diagnosis with dedicated fault alarm relay; modular internal structure for easy component replacement; supports standalone operation or multi-unit networking via SPA bus; strong electromagnetic interference resistance adapting to high-voltage substation environments; front panel buttons for local acknowledge, reset and parameter setting.
Wiring Instruction
Adopt panel flush mounting, all wiring screw terminals are arranged on the rear panel, each terminal accepts maximum 2.5 mm² wires. Connect dual redundant auxiliary power cables to dual power input terminals, connect field equipment alarm contacts to 16-channel signal terminals, wire external horn or indicator light to audible relay output terminals, link SPA bus twisted shielded cables to serial communication terminals, and reliably connect protective ground terminal to cabinet ground bar. Separate power cables and signal cables to avoid signal interference.
